Patented Feb. 15, 1944- 1 UNITED STATES I PATENT OFFICE v n AXLE BEARING SEAL William L. Scribner, Canton, Ohio, assignor to The 'lfimken Roller Bearing Company, Canton, Ohio, a corporation of Ohio Application May 18, 1942, Serial No. 443,352

4 Claims. My invention relates to axle bearing seals,

particularly to seals !or railway car axle and the like bearings of the type having a sealing ring encircling the axle, wherein a close fitting sealing ring is desirable, but wherein a loose fit is commonly provided by reason of the necessity for accommodating lateral play of the axle and wear of the bearing. The invention has for its Principal objects to accommodate such lateral play of the axle and wear in the bearings, while maintaining a close sealing ,flt between the sealing ring and the axle and providing a simple,

durable and inexpensive construction. Another Fig. 1 is a longitudinal sectional view of a railway car axle bearing seal embodying my invention: and a Fig. 2 is atransverse sectional view on the line 2-2 in Fig.1.

In the accompanying drawing is shown an end portion of a railway vehicle axle I having a wheel 2 on the end thereof, an axle housing 3 said carrier ring is a ring l8 of yieldable or resillent material and mounted in the end of said sleeve l6 of said carrier ring l remote from said washer portion I1 is a second similar ring I! of yieldable or resilient material, said rings l8 and 19 having their opposed inner peripheral portions 20 beveled. Interposed between said yieldable rings l8 and I9 is a rigid sealing ring 4 2| of substantially triangular section, two sides of said ring being engaged by said beveled por-- tions of said yieldable ring and the bore 22 of said sealing ring making. a close sealing lit with said axle I, but permitting rotary and axial movement of the axle therein, Said sealing ring 2| may be made of metal, micarta or other suitable material.

The yieldable ring l9 in the open end of the carrier l5 projects therefrom and the yieldable rings l8 and I 9 maybe compressed as desired, by regulating the distance that the carrier ring I5 is pressed into the socket H in the end plate Ill. The sealing ring 2| maintains a close sealing fit with the axle, being free to yield with the axle to accommodate lateral play thereof orlooseness in thebearing due'to wear or other cause. The yieldable rings l8 and I 9 form an additional sealing device preventing by-passing of oil or foreign matter around the sealing ring.

. The sealing device may be preassembled and terminating adjacent to the lace dithe wheel 2' and a taper roller bearing 4 interposed between the axle l and the end of said housing 2.

The cone '5 or inner bearing memberoi said bearing is mounted against an abutment ring 6 that is seated against a shoulder 'l on the axle,

with its small end facing the wheel}. The cup- 8 or outer bearing member is mounted in the end portion of the housing 3 and tapered bearing rollers 9 are interposed between said cup 8 and said cone 5. An end plate ll secured to the end of the housing, as by screws 1 I, has an inwardly extending annular rib l2 whlchbears against the end of said bearing cup 8. Bearing adjustment is obtained by means of shims II interposed between the housing 3 and said end plate ll.

"Said end plate has a cylindrical recess or i pocket u therein facing the wheel 2 and a mounting or carrier ring ii of angular section has its peripheral sleeve portion l6 pressed in said pocket ll. Mounted in said carrier ring l5 against the radial and or washer portion ll of mounted as a unit in the end plate of the. housing. Obviously the sealing device is compact, simple, durable and economical, as well as constituting an eflicient closure that maintains its tight sealing engagement with the axle, regardless of lateral play in the axle. Obviously the invention is not limitedto the details 01 bearing, axle and housing construction shown in the drawing and numerous changes may be made without departing from the invention so that I do not wish to I be limited to the precise construction shown.

What I claim is: l. A preassembled, unit handled axle bearing seal for wheeled axles and the like comprising a pair of spaced rings of yieldable material, a carrier ring therefor and a continuous sealing ring for said axle held between said yieldable rings. 2. A preassembled, unit handled axle bearing seal for wheeled axles and the like comprising apair of spaced rings of yieldable materiaL'a carrier ring therefor and a continuous sealing ring for said axle held between said yieldable rings,

said yieldable ringshaving beveled inner periph eral portions engaging the sides of said sealing 8- 3. An axle bearing seal for wheeled axles and yieldable material mounted in said angular supporting ring against the inner face of said washer portion, a ring of yieldable material mounted in said angular ring, spaced from said first yieldable ring, the opposed inner peripheral edges of said yieldable rings being beveled and a continuous rigid sealing ring of triangular section supported by engagement with the beveled portions of said yieldable rings, said sealing ring having a bore such as to have a running fit on said axle.

4. A preassembled, unit handled axle bearing seal for wheeled axles and the like comprising a ring of angular section having a sleeve portion adapted to be mounted in a housing and a radial washer portion, a ring of yieldable material mounted in said angular supporting ring against the inner face of said washer portion, a ring of yieldable material mounted in said angular ring, 1

spaced from said first yleldable ring and projecting beyond the end of said angular ring remote from said washer portion, whereby said yieldable ring, may be compressed by engagement of said projecting ring with a seal in said housing, the

opposed inner peripheral edges of said yieldable rings being beveled and a continuous rigid sealing ring of triangular section supported by engagement with the beveled portions of said yieldable rings, said sealing ring having a bore such as to have a running fit on said axle.
